Ascendex withdrawal fee is very affordable. The fee for Bitcoin withdrawal is just 0.0005 which is almost the same with other exchanges out there. Maybe there are still people looking for a fee lower than that. But for me that is enough, the most important in the exchange is the volume because it will be difficult for you to do a trade if there's a lack of orders in that specific pair. And also it's not attractive if people see there's no volume and it does mean that there are few users only.
